摘　　要：在分析空间相互作用理论及其可视化方法的基础上,针对现有的空间相互作用大小可视化方法的不足,提出一种邻近点间相互作用大小的可视化方法。该方法以可视化理论为基础,利用断裂点的特性确定可视化结果的大小,通过建立可视化规则优化可视化效果,实现了邻近点间相互作用大小的二维可视化,可有效地观察与分析空间实体间的相互作用大小。实例表明,该方法简单易行,有利于总体和个体的空间相互作用大小的比较,具有较强的直观性和可比性。Based on analyzing of the spatial interaction theory, visualization theory and the shortcomings of existing visualization methods in spatial interaction, the visualization method for the size of spatial interaction between adjacent points was proposed. The size of visualization result was determined by using the characters of break points. The visual effect was greatly improved through establishing visual rules. Based on these work, 2D visualization method for the size of spatial interaction between adjacent points was realized. The experiment results illustrate that this method is simple and superior to the existing methods in the case of visual impression and comparability.
